I'm sorry for not being so specific, first time asking for help online.
So, I did understand the logics behind a genetic algorithm and I'm trying to apply it without copying anyone's code. I wask kind of succesful, but the population doesn't evolve at all, it keeps creating individuals with random genes.
I think you might also get more input if you posted your code here instead of making people jump through hoops at another site to get to it. Also, this thread will be of no use to anyone else in the event that your code is removed from the other site.
